Selling stocks can be good but keep mind that if its profitable you should not do this, I think that if you really want it you can do it but I think its not a must because it can be both very profitable.
I still would more go for the bitcoin because the bitcoin is simply better it has a better price and its also that you can use it for more things.
Its just better in my opinion to go for yourself it has a good future to by the way,
